Generalised Linear Mixed Models testing for treatment effects on changes over time in testosterone concentration and ornamentation (comb area).


The dependent variables were log-transformed. Sequential model outputs are given.

Time: C1 (first recapture, when treatments were given) vs C2 (second recapture, 17 days after treatments). See Table 1.

HTREAT: Hormone treatments (T0: control implanted vs T+: testosterone implanted).

PTREAT: Parasite treatments (P0: purged of worms; P+: challenged with T. tenuis infective larvae).
